Don't have Facebook, not here for the drama anyway and i use my Tumblr like once a month. I still have Twitter but don't use it as much anymore, only to view trends and news. Don't intend on deleting them tho, i'd let them just die a natural death
But Facebook is definitely not as popular these days. The last time there were more than 200 people online was because of the election yesterday and I have 3,209 friends on Facebook.
